Heat and mass transfer in a packed bed reactor for calcium oxide/carbon dioxide chemical heat pump

摘要: In this study, a chemical heat pump using calcium oxide/carbon dioxide reaction system was discussed. order to establish the operational conditions of pump, storage and generation experiments were done under various pressure temperature in packed bed reactor. Decarbonation reactivity CaCO 3 higher at lower pressure, practical rate observed about 1023 K 0.1 atm. Carbonation reactions CaO proceeded almost equilibrium pressure. 1123 1.0 Then, an analytical model based on mass transfer proposed explain phenomena during carbonation bed. The enables us clarify detailed behavior carbonation. controlled mainly by influence gas flow indispensable for model. represented well experimental
